Yes, that's the connector for the stalk.

Please, anyone who has working cruise control, could you check what does Multiecuscan display for Cruise Control parameters after connecting to the Engine management?

Hello, I have JTD with 6pin brown connector and 2pin counterpiece. So I wired the 4 other wires + 12V to my CC stick. Then I enabled it in MES, so it actualy lights the LED. All CC buttons are working, but when I tried it driving, it didn't work at all.
In MES I get P0703 Brake signal error every time I press the brake. The switch should be working fine and its connector has 4 wires.

What should I do? New brake switch?

OK, so I connected the pin A02 from BLACK D4 connector (purple/white in my case) to +12V on battery and now it works.
The question is - where should I get 12V from? The fuse box under steering wheel F35? And should I connect it back to D4, or can I wire it straight to brake connector? (that would be very easy)
